Qomolangma is the third mountain of the Himalayas, so people call it the Third God Mountain in Tibetan language.
Qomolangma is very famous and it is higher than any other mountain in the world. Its newest height is 8,848.86 meters. At the height of 8,000 meters, there is only 30% O2 and the human body can only stand this height for a few days, so it is dangerous for humans to climb higher. But many climbers want to challenge themselves. As Alan Arnette, a mountain climber from America, said"Climbing mountain s drives you to look deep inside yourself, and lets you find out whether you are strong enough in mind when you want to stop."
It's a good thing that Qomolangma gives people a chance(机会) to become strong-willed (意志坚强的) when they are trying to achieve their dreams. However, Qomolangma is in danger these years because many people leave their waste behind, such as water bottles and plastic (塑料的) bags. They cause the environmental pollution for Qomolangma. Many animals would die after eating the plastic bags. Luckily, many volunteers from all over the world came to Qomolangma to join in the clean-up activity. A volunteer advised,"Mountain climbing lovers should always take good care of themselves,and at the same time, take good care of Qomolangma."
